The story operates across two timelines: a Cold War-era expedition in the 1980s discovers the cave after a dynamite accident, and a present-day scientific team returns to the same site. These parallel narratives reveal how the cave's secrets persist across generations. The contrast between the two periods explores how exploration and ambition can unleash unknown life forms.

The mutation theme centers on a parasitic organism that develops in the cave's perpetual darkness and threads through all known cave organisms. The parasite originated underground and evolved to exploit the isolation, eventually spreading to characters like Jack through scratches. The mutation culminates in physical changes like mutated eyes and the terrifying potential to spread beyond the cave to the surface world.

The Cave features a high-intensity tone with a fast-paced succession of crises, from sudden creature attacks to fatal accidents, leaving little room for calm. The mood is tense and anxious, driven by numerous deaths, the horror of parasitic infection that physically mutates characters, and the breakdown of trust within the group. The ending is ambiguous, offering temporary escape but implying the threat has spread to the surface.
